Meteorologist expects severe drought and heavy rain events to worsen globally

A University of Oklahoma meteorologist, Elinor R. Martin, expects severe drought and long-lasting rainfall events to worsen in the future.
The Caribbean and Central America will have more extreme droughts and the north and northeast of North America can expect more extreme heavy rain events. 
Around the world, some places will see droughts and heavy rain events become more intense, longer lasting and more frequent.
Martin points to a changing climate as the reason these events will worsen and defines droughts and rain events by using a standardized rainfall index to compare events between regions and seasons.
